[I realize you intend to use physical machine for DevStack, still I thought I'd post this here.] FWIW, this is the minimal localrc contents (be sure to edit ENABLED_SERVICES config directive to fit your needs) I use in my DevStack Neutron setup in a virtual machine. This setup uses nested KVM (LIBVIRT_TYPE=kvm in localrc does it) -- for it work, the host needs to have nested KVM enabled: $ modinfo kvm_intel | grep -i nested parm: nested:boolkvm 435079 1 kvm_intel More details on that here, in case anyone else finds it useful. Once the stack.sh is complete, I do some tasks Neutron expects: - Create a new private network - Create a new private subnet (on the above private network) - Create a router - Associate the router to an existing external network by setting it as its gateway - Associate the private network interface to the router - Add Neutron security group rules for ICMP and SSH  https://kashyapc.fedorapeople.org/virt/openstack/minimal_devstack_localrc.txt  http://kashyapc.fedorapeople.org/virt/procedure-to-enable-nested-virt-on-intel-machines.txt -- /kashyap _______________________________________________ OpenStack-dev mailing list OpenStackemail@example.com http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
